The Pittsburgh Steelers are entering the 2024 season with a fairly complete roster. The only positions that are still in need are wide receiver and slot corner. Despite months of trade rumors, the NFL Draft passed without the Steelers acquiring a wide receiver. Instead, they added a stable of WR3 types for competition and drafted Roman Wilson in the third round.
That still leaves some room for a possible trade, but the timetable for that is up in the air. Post June 1st allows for some cap maneuvering on the part of the team trading away a receiver, so the range of possible dates is anywhere from June 1st to September 7th when Week 1 of the season begins.
